Hoʻohana nui ʻia ka panela Puf i ke kūkulu ʻana, ka mālama anu ʻana, nā hale ʻoihana, a me nā hale modular, mahalo i kā lākou hana insulation kiʻekiʻe a me ka wikiwiki o ke kau ʻana. ʻOiai ke mahalo nei nā mea kākau hale a me nā mea kūkulu hale i kā lākou hana, ʻokoʻa nui ke kumukūʻai ma muli o nā kumu helu he nui.
Mānoanoa o ka Panel a me ka hana insulation
Pili pono ka mānoanoa o ke kumu o ka panela sandwich PU me kona kumukūʻai. ʻO ka mānoanoa maʻamau mai 40 mm a 250 mm, me nā panela mānoanoa e hāʻawi ana i ka insulation thermal maikaʻi aʻe (waiwai U haʻahaʻa) akā koi aku i nā mea maka hou aku.
ʻO ke kumukūʻai o kahi panela Puf 100 mm he 20-30% ʻoi aku ma mua o ka mea like he 50 mm ma muli o ka hoʻonui ʻia o ka nui o ka polyurethane foam a me ka hoʻomaikaʻi ʻia ʻana o ka R-value, hiki ke hōʻemi nui i nā ukana hoʻomehana a me ke anuanu ma luna o ke ola o ka hale.
Hoʻopilikia ka pono wela i ke kumukūʻai no ka mea ʻo ka hoʻokō ʻana i kahi conductivity wela haʻahaʻa (ma kahi o 0.022 W/m·K no PU) e koi ai i ka hoʻopili ʻana o ka huʻa pololei a me ka kaohi maikaʻi.
Mea Koʻikoʻi a me ka Density
ʻO ka Polyurethane ponoʻī kekahi mea nui e hāʻawi ana i ke kumukūʻai. Hāʻawi ka ʻōnaehana paʻa o ka PU foam i ka insulation maikaʻi loa i hoʻohālikelike ʻia me nā koho ʻē aʻe e like me EPS (expanded polystyrene), akā ʻo kāna mau mea maka—polyols a me isocyanates—he mau mea loaʻa petrochemical me nā kumukūʻai loli. Hōʻike ka ʻikepili ʻoihana he 60-70% o nā lilo hana panela holoʻokoʻa ke kumukūʻai o nā mea maka.
Eia kekahi, hoʻopilikia ka nui o ka huʻa i ka hana a me ke kumukūʻai. Hāʻawi ka PU kiʻekiʻe-density i ka ikaika mechanical ʻoi aku ka maikaʻi a me ka hoʻohaʻahaʻa ʻana i ka thermal elemakule akā hoʻonui i ke kumukūʻai ma muli o ka hoʻohana nui ʻana i nā mea a me ka paʻakikī o ka hana ʻana. Hiki i ka panela Puf me ka nui o ka core density ke kumukūʻai he 15-25% ʻoi aku ma mua o nā mana haʻahaʻa-density.
Nā Mea Hana Kūlohelohe
ʻO nā panela sanwika he kumu PU i hoʻopaʻa ʻia ma waena o ʻelua mau ʻaoʻao metala. Hiki i kēia ke kila galvanized, kila i pena mua ʻia, a i ʻole alumini. ʻO kekahi mea hana alakaʻi, e like me Harbin Dongan Building Sheets Company e hāʻawi i ka panela puf me nā panela alo Al-Mg-Mn, hiki ke hoʻomāmā i ka panela sanwika, ʻoi aku ka pale ʻana i ka pala, a ʻoi aku ka ikaika.
ʻO ke kila galvanized maʻamau ka mea alo maka waiwai loa a hāʻawi i ke kūpaʻa kūpono i ka pala, ʻoiai ʻo ke kila i pena mua ʻia me nā uhi PVDF a i ʻole polyester e hoʻohui i ka lōʻihi a me ka nani. ʻOiaʻiʻo, e hoʻonui ia i ke kumukūʻai hana. ʻOi aku ka māmā o nā alo alumini a ʻoi aku ka pale ʻana i ka pala akā e ʻoi aku ke kumukūʻai ma mua o ke kila.
He mea nui nō hoʻi ka mānoanoa o nā ʻili hao. Ma keʻano laulā, ʻo ka mānoanoa o ka ʻili kila he 0.4-0.6 mm. Hiki i ka Hui Dongan ke hāʻawi i nā panela me nā ʻili hao he 0.8mm ka mānoanoa. Hoʻomaikaʻi ka ʻili mānoanoa i ka paʻakikī o ka panela puf a me ka hana hāpai ukana, ʻo ia hoʻi ke kumukūʻai kiʻekiʻe.
Nā Loiloi Ahi a me nā Kūlana Palekana
Hoʻokō pinepine nā panela Puf maʻamau i nā helu ahi kaulike e like me ka papa Euro E. Eia nō naʻe, ʻo nā papahana, e like me nā hale lehulehu, nā kula, nā haukapila, e koi ana i nā pae palekana kiʻekiʻe. Koi nā panela e hoʻokō ana i ka hana ahi kiʻekiʻe i nā ʻano hana pale ahi kūikawā a i ʻole nā kiko ʻē aʻe, e like me PIR, e hoʻonui ana i ka paʻakikī o ka hana a me ke kumukūʻai.
Nā Lako no ka Hana ʻana i nā Panel Sandwich
He hopena nui ko nā lako hana i ka maikaʻi o nā panela sandwich. Hiki i ka laina hana holomua a hoʻohui ʻia ke hōʻoia maikaʻi i ka huʻa like o ka mea kumu polyurethane a me ka hui pū ʻana o ka papa metala o ka mea kumu.
Hoʻopilikino a me nā hiʻohiʻona kūikawā
ʻOi aku ka maikaʻi o ke kumukūʻai o nā panela PU maʻamau ma muli o ka hana ʻakomi. ʻO nā nui maʻamau, nā ʻano kū hoʻokahi, nā ʻaoʻao lihi kūikawā, a i ʻole nā uhi holomua no ka UV, anti-condensation, a i ʻole nā hoʻopau hoʻolālā e hoʻohui i ke kumukūʻai.
Eia kekahi laʻana, ma waho aʻe o nā mea maʻamaunā panela sanwika, Hiki i ka ʻoihana ʻo Dongan ke hāʻawi i nā panela sandwich hoʻonaninani. Hiki i nā mea kūʻai ke koho, a hoʻopilikino paha, i ke ʻano o ka ʻili metala e like me kā lākou makemake ponoʻī a me ke ʻano o ka hale. ʻO ka hana ʻana o nā ʻano i hana ʻia me ka maʻamau ʻo ia hoʻi ka pono e hana ʻia kahi ʻōmole metala kaʻawale, a e hōʻike ʻia ke kumukūʻai o ka ʻōmole i ke kumukūʻai o ka huahana i hoʻopau ʻia.
